What size are bifold windows?
The size naturally depends on the specific design of the bi-fold window, along with its manufacturer. Due to the variety of offers, it is not possible to clearly determine the exact dimensions of all available doors, but when it comes to the width of the panel of internal bi-folds it usually varies from 400 to 1000 mm, for illustrative purposes:
- British manufacturer Origin produces aluminum bi-folds where individual sashes range from 400 mm to 1200 mm wide
- Timber Bi Fold’s wooden panel comes with a maximum panel width of 1000 mm
| Remember, that you can choose between having a smaller amount of larger panels or a higher number of smaller ones. |
When it comes to height, external bi-folds are slightly taller than their internal counterpart. According to https://www.vufold.co.uk/: “for UK bifold doors, the average standard height is 2078 mm (6.8 ft) for internal bifolds and 2090 mm (6.10ft) for external”.

How much do bifold exterior doors cost?

Are bifold windows energy efficient?
Compared to other systems, bi-fold does not provide such good air tightness. That is because there is only a brush at the bottom of the sash, which can cause draft, so it is rather suitable for public places (for example, a café) than houses (unless they are located in a mild climate).
As you can see, the purchase of an aluminum sliding system is a significant investment. It requires cooperation with experienced door and window fitters. Present all the pros and cons to your client so that they can make an informed decision that they will not regret later.
